MANA Turret are currently easily used as griefing tools. They litter the battlefield and can be used by enemies as Friendly-Fire shields. Make the MANA Turrets automatically deconstruct if the Engineer is dead or far enough from the turret.
It's amazing how something that gets you killed 0.5 of a sec after standing behind it can be so tough to get rid of. Why not just nix it from the game. The things are totally worthless, they shoot frozen peas for ammo, and have a big opening right were your head is, so snipers can get a freebee.
I've never gotten headshot while hiding behind my trusty MANA wall. Granted, I don't actually intend to shoot with the turret since it's rubbish in regards to that except in some corner cases, and I'm usually crouching, but each person to their own playstyle.
